FLASH y LIGHT.

Application led March 22, 1920. Serial No. 867,928.

To all lwhom. 'it may concern:

Be it known that I, F RED EVANS, a citizen of the United States, residing in the city of Summit, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Flash Lights, of which the following is a full, clear, and exact description. n

The object of this invention is to provide a flash-lamp of simple and economical construction, and one that is designed particularly for use by policemen, firemen, watchmen and others who may find it desirable and advantageous to carry a flash-lamp suspended from the neck.

Another object is to provide a flash-lamp having a circular `metallic casing, made of separable parts, and also having all of .its working parts mounted on a frame which may be entered in the casing as a unitary structure.

A further object is 'to provide a flashlamp which, while carried suspended from the neck, may be readily actuated by pulling a flexible cord.L

My invention is illustrated in the accompanying drawin which forms a part of this application, an in which i 1 represents an elevational view with the ront casing section removed, showing the interior of the Hash-lamp.

Fig. 2" is a central vertical, cross-section,

taken on the'line 2-2 of Fig. 1.

Fig. 3 is a fragmental detail view, illustratin how the casing flanges are overla pe and connected.

'teferring to the drawing in detail, the numeral 4 represents the front casing section, consisting of a circular plate formed with a rim flange 5; and the numeral 6 represents a rear circular plate similarly formed with a flange 7, which engages within the flange 5, and which is provided-with an exterior bead 8,A ormin an abutment for the edge of flange 5. 'he sections 4 and` 6, thus formed', are madepreferably of pressed metal, such as sheet iron, sheet aluminum, or the like. The front plate 4, adjacent the Hang? 5, is rovided with a circular opening w ose de ning'edge 9 is bent inwardly and upon itself to provide -a recessed ring, 1n which is secured the iange of a reflector 10, formed with a projecting socket 11. An incandescent lamp 12 is screw-threaded into the the socket; and a lens 13 is set in the ring 9 against the refietor, the outer ed e14 of the ring then being turned inwar y upon the lens to hold the parts firmly in place.

For supporting the working parts, I emplo a skeleton frame consisting of front an rear plates 15 and 16, connected in parallelism by the arbors 17, 18, 19 and 20, the said arbors 17 and 18 more specificall connecting the offset regions 21 cast on t e respective plates for this purpose.v As clearly shown in Fig. 2, the arbors connect these plates in such spaced relation that the late 16 -will rest on' the back plate 6, and) the plate 15 on the front plate 4, when the casing sections are assembled; and it will be further observed that the plate 16 reaches diametrically across the back plate 6, in a path behind the lamp, while the top v extremity of the plate 15 meets the-ring 9 and is fashioned to conform therewith. As a means of holding this skeleton frame ixedly ,in position, the flanges of the casing sectionsrare made with humps or inner deformations 22, designed to embrace the lower ends of the plates 15 and 16,l and also the top end of the atter.

Fulcrumed on the Varbor 17 is a bowed lever 23, formed with a sector gear 24, designed to mesh with a pinion 25, which is mounted on the arbor 18, together with a gear wheel 26 with which it is rigid. Mounted on the arbor 19 is a pinion 27 which receives its movement from the gear wheel 26, and to this pinion is attached a gear wheel 28, which imparts its movement to a pinion 29, mounted on the arbor 20 and pinned fast to a ratchet wheel 30. Adja-` cent this ratchet wheel, there is loosely mounted on the arbor 20l a permanent magnet 31, formed with a plurality of branches 32, between which are a plurality of armatures 33, coil wound in series, and attached to a guard sleeve 34, which surrounds-the arbor 20 and is xedly secured to the plate 16. Engaging the teeth of the ratchet wheel 30 is a pawl 35, pivoted at 36 to av branch of the magnet, and-'fl magnet is rotated the ratchet wheel is turned against th awl.

urges the pawl into engagement withqthe p A spring 37,' Apinned at 38 to a magnet branch, normally ratchet teeth. When the ratchet Wheel is turned reversely, or in a direction that carries its teeth away from the pawl, the latter is forced to rise on the teeth, in consequence whereoitl the magnet is not turned.\

Attached to the extremity of the bowed lever 23 is a flexible core 39, which drops dependingly through an opening 40, provided in the casing flange, and to the lower end of which is attached a ring 41. The speed multiplying gears above described are actuated to spin the magnet about the coils each time the flexible cord 39 is drawn downwardly with a quick stroke. A spring 42, connected betweenrthe end of the lever 23 and the plate 16, inlluences the movement of the gearing reversely, but Without rotating the magnet, after downward pull on the exible cord.

One end 43 of the armature winding leads to a conducting spring 44 with which it is secured by a binding post 45, on a plate of insulating material 46, attached to the back plate 16. This conductor 44 is arranged to engage a terminal of the lamp base. The other end 47 of the armature winding is grounded at 48 on the plate 16, to which the electric return is made through the lamp base, reflector and casing parts.

ln order to suspend the structure from the neck of the carrier, the casing flange 7 is provided on opposite sides of the plate 16 with eyelets 49, behind which are engaged the knotted ends of the flexible cord 50 :Maratea (fragmentally shown), which is adapted to be looped around the neck of the wearer.

When the casing sections have been assembled, they may be securely, though removably, connected by means of screws as 51.

Having thus described my invention, what I claim isz- A lash light comprising in combination with a drum having an incandescent lamp disposed to project light rays through the face of said drum, said lamp being near the periphery of the drum on one side thereof, a current generator in said drum diametrically opposite said lamp, and electrical connections between said generator and lamp, of a gear train in said drum adapted to impart rotary motion to said generator in one direction, said gear train including a pawl and ratchet device permitting the gears to return to initial position witlioutyaliecting the generator, means for causing the gear train to normally assume its initial position, means for manually actuating said gear train, said means consisting of a sector and lever, and a flexible cord extending through said drum for actuating said sector and lever.-

This specification signed and witnessed this eighth day of March, 1920.
